Spatiotemporal variability of hydrologic response : an entropy-based approach using a distributed hydrologic model
Basin hydrologic response pertains to the partitioning of precipitation into stream-flow, evapotranspiration, and change in storage. The ability to explain or predict the response has many applications e.g. flood forecasting, water budget studies, and design of hydrological observing systems. …

The use of a distributed hydrologic model to predict dynamic landslide susceptibility for a humid basin in Puerto Rico
This thesis describes the use of a distributed hydrology model in conjunction with a Factor of Safety (FS) algorithm to predict dynamic landslide susceptibility for a humid basin in Puerto Rico. The Mameyes basin, located in the Luquillo Experimental Forest in Puerto Rico, was selected for modeling …

Modeling the Effects of Forest Road Density on Streamflow in the Blue Ridge Mountains
… effects of forest harvesting on water yields. A distributed hydrologic model (DHSVM) was calibrated for a 760 ha watershed in the Blue Ridge Mountains of North Carolina. The impacts of forest road density were evaluated by running the model using uniform input parameters but changing road …

On evaluating small-scale variations of hydrologic processes in time and space
… focuses on representing the small variations in hydrologic properties at various scales. Numerical experiments are used to explore the effects of the distributions of various hydrologic processes at various scales. The model used in this study is a physically based distributed hydrologic model …

Precipitation Estimation Methods in Continuous, Distributed Urban Hydrologic Modeling
… (QPE) remains a key area of uncertainty in hydrological modeling, particularly in small, urban watersheds which respond rapidly to precipitation and can experience significant spatial variability in rainfall fields. Few studies have compared QPE methods in small, urban watersheds, and …

Hydrological responses to the synergistic changes in climate and land cover in the alpine pastoral region
Quantifying the hydrological responses to climate change and land use and land cover (LULC) change is imperative for sustainable river basin management. In this study, hydrological regimes of the upper Lancang River Basin under environmental changes are assessed using a semi-distributed hydrologic …

High-resolution soil moisture mapping by a proximal ground penetrating radar: A numerical, laboratory and field evaluation
… state variable acting in many environmental, hydrologic and climatic processes. There is thus a pressing scientific demand for revealing the soil moisture dynamics in the biosphere at various temporal and spatial scales. Despite the huge development of remote sensing of soil moisture …

Evaluation of climate change impacts on the hydrologic response of a sparsely-monitored basin in Sardinia, Italy, through distributed hydrologic simulations and hydrometeorological downscaling
The water resources and hydrologic extremes in Mediterranean basins are heavily influenced by climate variability. Modeling these watersheds is difficult due to the complex nature of the hydrologic response as well as the sparseness of hydrometeorological observations. In this work, we first …

Hydrologic modeling using triangulated irregular networks : terrain representation, flood forecasting and catchment response
Numerical models are modern tools for capturing the spatial and temporal variability in the land-surface hydrologic response to rainfall and understanding the physical relations between internal watershed processes and observed streamflow. This thesis presents the development and application of a …

The role of topography in the emergence of African savannas
… simulations are performed using biospheric model, IBIS, and distributed hydrologic model, SHE. We, first, estimate the amount of rainfall required for trees and grasses under a certain atmospheric condition. Here, the variation of rainfall is prescribed to force a similar variation of soil …

A distributed modeling approach for evaluating hydrological effects of rain gardens in urban watersheds
… of recognized methodologies to estimate their hydrologic effects in urban watersheds under a continuous rainfall period. It is expected that rain gardens will have a significant effect in the reduction of peak discharge and volume for a range of different storms magnitudes including less …

MODELLING CURRENT AND FUTURE WATER RESOURCES AVAILABILITY IN AN ALPINE CATCHMENT EXPLOITED FOR HYDROPOWER PRODUCTION
… Alpine environment. This study focused on the hydrologic modelling of the Valgrosina valley (Italian Alps). It covers an area of about 130 km2 ranging from 1200 to 3400 m a.s.l. and is divided into two main branches: the Sacco valley (western side) and Eita valley (eastern side), where a dam …

Guiding green stormwater infrastructure planning through socio-ecological vulnerability: An integrated and spatially scalable prioritization framework
… uses a graph-based approach with a simplified distributed hydrologic model and mixed-integer linear programming to maximize the potential delivery of GSI benefits to the most vulnerable areas. This enables a better understanding of the impact that multiple stakeholder opinions could have on the …

Diagnostic analysis of runoff partitioning at the catchment scale
… scale is necessary to constrain and improve hydrological predictions at catchment scale, especially in ungauged catchments. This dissertation systematically investigates the controls of climate, soil and topography on runoff partitioning at the catchment scale, and consequent of runoff …

Modelli di preannuncio delle piene in piccoli bacini ed incertezze legate alla densita' della rete pluviometrica.
Small catchments with fast hydrological responding geomorphology are commonly prone to Flash Floods, which have to be predicted on the basis of meteorological forecast and radar nowcasting, rather than continuously monitoring river water levels. Moreover, real-time rainfall observations at high …
