Abstract
Flood hazard map plays
an important role in conveying flood risk information to decision makers as well
as the general public for civil protection purposes and relief operations. In
order to prevent or reduce human and economic losses, reliable and accurate
information regarding to the risk associated with the flooding is undeniably
necessary. As a consequence, the demand of higher quality flood hazard maps is
growing. The area in the transboundary Vipava/Vipacco river basin across the
Italian-Slovenian border has severely experienced flooding, especially the
densely populated town Miren and the downstream village of Savogna d Isonzo.
Based on some hydrological and hydraulic studies it is believed that the
flooding problems of Vipava river is not only a result of its complicated flow
conditions but it might also be influenced by backwater effect caused by the
river Isonzo. This study aims to perform a set of flood hazard maps by 1D model
(HEC-RAS) and by 2D model (FLO-2D) mainly for civil protection purposes and
investigate some sources of hydrological and hydraulic uncertainty, including
the backwater effect. The area of interest is one of 6 case studies of KULTURisk
project (www.kulturisk.eu) funded by Seventh Framework Programme.

Posledice poplav na
naravnih zavarovanih območij niso dobro raziskane, e posebej pa v porečju reke
Save. Ne vemo e, kakni bodo učinki podnebnih sprememb poplav na naravne
habitate mokrič. V magistrski nalogi sem raziskovala vpliv hidrotehničnih
ukrepov in podnebnih sprememb na pogostost poplav na dveh lokacijah, naravni
park Lonjsko Polje in Obedska Bara. Analiza je bila izvedena z uporabo
hidrolokega modela z avtomatsko kalibracijo in podatkov o napovedi podnebnih
sprememb. Rezultati so pokazali povečanje poplavnih pretokov za nizke frekvence,
kar bi lahko povzročilo dalje trajanje poplav na obravnavanih območjih. Na
podlagi tudije, Baptist in ost. (2006), to lahko poslaba vegetacijo na
mokriču Lonjsko Polje. Na območju Obedska Bara ne pričakujemo nobenih učinkov
vpliva podnebnih sprememb poplav. Zaključek je, da bo obseg poplav naračal, kar
bi lahko negativno vplivala na varovana območja. Potrebujemo več tudij, ki bi
zagotovile bolje razumevanje problema in ustrezno upravljanja območij, vključno
z začito pred poplavami in reevanjem okoljskih problemov.

Abstract
The subject of impacts
of floods on Natural Protected Areas is not very well studied, especially in the
Sava River Basin, and the effects of long inundation on natural habitats of
wetlands are not clearly recognized. In this thesis the impact of structural
measures and climate change on flood frequency was investigated with regard to
two sites, Lonjsko Polje Nature Park and Obedska Bara Nature Reserve. The
analysis was performed using a hydrological model with automatic calibration and
data transformed according to the climate predictions. The results showed an
increase in flood peaks for low frequencies, what could cause a longer duration
of inundation of the areas. Based on study developed by Baptist et al (2006)
this might deteriorate the vegetation of the Lonjsko Polje wetland. In terms of
the second area no effects of floods are recognized. The conclusion is that the
magnitude of floods will increase, what could negatively affect the protected
sites, however more studies need to be undertaken to provide better
understanding of the problem and assure proper management of the areas including
flood protection and environmental issues.

Povzetek
Po tragičnem dogodku 17. novembra 2000, ko se je
zemeljski plaz z območja Sto, ki je bil posledica dolgotrajnih intenzivnih
padavin, preoblikoval v drobirski tok in povzročil smrt sedmih prebivalcev Loga
pod Mangartom ter poruil est hi v Logu pod Mangartom, se je stroka pričela
bolj intenzivno ukvarjati s problematiko drobirskih tokov. Raziskovanje
drobirskih tokov v svetu se je pričelo po letu 1970. Tematika pokriva področja
geologije, geomehanike, hidrologije, hidromehanike in klasične mehanike, zaradi
elektrokemičnih vezi pa sega tudi na področje fizikalne kemije. V nalogi so
predstavljena masna premikanja zemljin, med katera so razvrčeni tudi drobirski
tokovi. V nadaljevanju so podane nekatere mehanske in dinamične značilnosti
drobirskih tokov. Navedeni so pogoji, pri katerih taki tokovi nastanejo, opisana
je značilna sestava drobirskih tokov in fizikalne lastnosti z nekaterimi
posebnostmi, ki so posledica reolokih lastnosti drobirskih tokov. Predstavljeni
so osnovni teoretični modeli, ki ponazarjajo gibanje drobirskih tokov in so
osnova za določitev vpliva reolokih lastnosti pri njihovem matematičnem
modeliranju. Sledi predstavitev uporabe dvodimenzijskega matematičnega modela
PCFLOW 2D, ki je bil razvit na Univerzi v Ljubljani, na FGG, KMTe in s katerim
je bilo analizirano območje Loga pod Mangartom. Izdelana je analiza
občutljivosti matematičnega modela na tri reoloke parametre: viskoznost, mejno
strino trdnost in disperzivnost. Prav tako je bila izdelana analiza vpliva
gostote računske mree in izbire vrste robnega pogoja. Z matematičnim modelom so
bili nato določeni vplivi in optimizacija predlaganih ureditev. V
zadnjem delu naloge so podane gradbene in negradbene metode in načini varovanja
pred drobirskimi tokovi ter napotki za nadaljne delo pri raziskovanju drobirskih
tokov.
Ključne besede:

Abstract
On November 17, 2000, a landslide from the area of
Stoe, which was the consequence of long-term intensive rainfall, transformed
into a debris flow, caused the death of seven inhabitants and demolished six
houses in the village of Log pod Mangartom. After this tragic event, different
professionals in Slovenia started to get more involved with the problems of
debris flows. On the contrary, the research of debris flows throughout the world
started after 1970. This research field includes geology, geomechanics,
hydrology, hydromechanics and classical mechanics, and, due to electrochemical
bonds, it also reaches to the area of physical chemistry.
The thesis deals with mass movements, among which
belong also debris flows. In the sequence also some mechanical and dynamical
properties of debris flows are presented. The thesis states the conditions under
which such flows emerge, and the typical composition of debris flows. Physical
properties with some special aspects, which are the consequence of rheological
properties of debris flows, are described. The basic theoretic models,
representing the movement of debris flows, which are the base for defining the
influence of rheological properties at their mathematical modelling, are also
dealt with. Next follows the presentation of the use of the two-dimensional
mathematical model PCFLOW 2D, developed at the University of Ljubljana, Faculty
of Civil and Geodetic Engineering, Chair for Fluid Mechanics. This model was
used to analyse the area of Log pod Mangartom. A sensitivity analysis of the
mathematical model was elaborated, taking into account three rheological
parameters: viscosity, yield strength and dispersivity. Also, the analysis of
the influence of the computational network density and the definition of the
boundary condition was elaborated. With the help of the mathematical model, the
influences and the optimisation of the proposed river regulation works were
defined.
In the last part, the thesis suggests the structural and
non-structural measures and methods of protection against debris flows, as well
as the directions for further work at the research of debris flows.

Razvili in
preiskusili smo merilni instrument za merjenje pospekov. Pri meritvi ni povezan
z zunanjo opremo. Izmerjene pospšeke shranjuje v notranji statični pomnilnik z
naključnim dostopom. Instrument je okrogle oblike in je hermetično zaprt. Lahko
ga odpremo, da zamenjamo baterijo ali ga poveemo z osebnim računalnikom po
merjenju, ko meritev s serijskim prenosom prenesemo na osebni računalnik.
Naredili smo več testnih meritev in dva niza meritev pri kontroliranih
hidravličnih pogojih. Meritve analiziramo s programsko opremo na osebnem
računalniku. Razvili smo sistem za avtomatsko razpoznavanje trkov v signalih
pospeka s programskim paketom Matlab v5.3, Mathworks. S statistično analizo
avtomatsko določenih trkov pri kontroliranih hidravličnih pogojih smo ugotovili,
da obstaja najbolja linearna korelacija med povprečno silo trkov in
brezdimenzijsko strino napetostjo vodnega pretoka. Odvisnost med silo, ki
nastopi pri trku, in časom med tem trkom in naslednjim, pokae, da bo pri
velikih silah čas do naslednjega trka verjetno večji. Z analizo enega signala
meritev pospekov pri kontroliranih hidravličnih pogojih smo izlučili
parametre, ki predstavljajo značilnosti trkov in prikazali njihovo spreminjanje
v času signala. Prikazali smo tudi zaporedje trkov na obodu krogle.

Abstract
We have
developed and tested an istrument for acceleration measurements. In the phase of
measurement it is not atached to any external equipment. The measured
accelerations are stored internally in a static random access memory. The
instrument has a spheric shape and is hermetically closed. It can be opened to
change a battery or to connect to a personal computer via serial communication.
Namely, in the phase of download the internally stored measurement is
transfered to a PC. We have performed various test measurements and two sets of
measurements in controlled hydraulic conditions. The measured and downloaded
data is analysed on a PC. We have developed a system for an automatic
recognition of impacts in the acceleration signals with a commercial software
package Matlab v5.3, Mathworks. Statistical analyses of the impacts in
controlled hydraulic conditions revealed that the best linear corelation exists
between the force of impacts and non-dimensional shear stress of the water flow.
The depedancy between the force of impact and the time lag until the next impact
shows that greater force means probably greater time lag until the next impact.
By analysis of one measurement of accelerations in the controlled hydraulic
conditions the parameters that represent the properties of impacts were shown in
the time of the sygnal. We have shown also the impacts presented on the surface
of the sphere.
