Global spatial optimization with hydrological systems simulation:application to land-use allocation and peak runoff minimization
Global spatial optimization hydrological systems simulation land-use allocation peak runoff minimization
2010/2/20
A general methodology is presented to integrate complex simulation models of hydrological systems into optimization models, as an alternative to scenario-based approaches. A gradient-based hill climbi...
NUMERICAL SIMULATION OF THE RAINFALL-RUNOFF PROCESS ON A DAILY BASIS
NUMERICAL SIMULATION RAINFALL-RUNOFF PROCESS DAILY BASIS
2009/10/29
A digital model has been devcloped for the simulation of the rainfall -
runoff process of rural watersheds. Input data are daily values of prccipitation
and temperature together with mean monthly po...
Upper Layer Observations and Simulation Using Kraus and Turner's Model in the Gulf of Finland
Upper Layer Observations Simulation Kraus and Turner's Model Gulf of Finland
2009/10/29
There are strong seasonal variations in the depth of the thermocline and in the
sea surface temperature in the western part of the Gulf of Finland. A
numerical model, developed by Kraus and Turner, ...
A spatially distributed model for the simulation of snow accumulation and
melt is presented. Watershed information on topography, vegetation and soils
in digital terrain models (overlays) serve as t...
Application of Soil Water Flow Theory in Field Simulation
Application Soil Water Flow Theory Field Simulation
2009/10/28
A numerical model based on a finite difference approximation of the basic
differential equation for soil water flow is described. The equation includes a
sink term representing moisture extraction b...
Results of runoff simulations from various basins using a snowmelt runoff
model were analyzed in order to predict the accuracy of simulations in future
applications of the model. It was found that t...

Groundwater Response Conceptual Models Three Case Studies
2009/10/28
A conceptual runoff model is modified and applied to groundwater observations
in an unconfined till aquifer, a confined aquifer under a clay deposit and
a large unconfined esker aquifer. The results...
Stochastic Simulation of Evaporation Data for Australia
Stochastic Simulation Evaporation Data Australia
2009/10/28
Stochastic models are developed to simulate annual, monthly and daily
evaporation data for Australia. For annual and monthly synthesis, the
evaporation values are generated independently and depende...
Simulation of the Impact of Combined Sewer Overflow on Rivers
Simulation Impact Combined Sewer Overflow
2009/10/28
Combined sewer overflows can in some cases cause critical oxygen concentrations
in small rivers. The traditional design criteria for the overflow structures
is not specificly related to this effect....
Modelling of Unsaturated Flow in Heterogeneous Soils Part 11:Stochastic Simulation of Water Flow over a Field
Unsaturated Flow Heterogeneous Soils Stochastic Simulation
2009/10/27
Modelling of soil moisture conditions in spatially variable fields is treated using
stochastic methods. Spatial variability of moisture content in a vegetation covered
field is partly caused by fiel...

A digital simulation model has been presented for locating the steady state
stable brine cone position beneath partially penetrating wells tapping from the
fresh water zone overlying a saline zone i...
Simulation of Surface Runoff and Pipe Discharge from an Agricultural Soil in Nothern Sweden
Surface Runoff Pipe Discharge Agricultural Soil Nothern Sweden
2009/10/27
In order to test the ability of a physically based water and heat model to predict
surface runoff and pipe discharge, adaptations were made to an agricultural
field in the north of Sweden. A five-ye...
The flow caused by a dam breaking across its entire length can be approximated
by a one-dimensional, unsteady flow model in form of the St. Venant
equations. In this model, the flow is governed by t...
