Simulation of Groundwater Response by Conceptual Models-Three Case Studies
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...
Investigation of the Influence of Rainfall Movement on Runoff Hydrograph Part I1-Simulation on Real Catchments
Investigation Influence of Rainfall Movement Runoff Hydrograph Real Catchments
2009/10/28
Work presented here consists of two parts: the first part, presented before as a
separate paper (Niemczynowicz 1984b), described studies performed on conceptual
catchment, the secoGd part presented ...

Investigation Influence of Rainfall Movement Runoff Hydrograph Conceptual Catchment
2009/10/28
Work reported here consists of two parts: the first part describes studies
performed on a conceptual catchment, the second part, presented as a separate
paper, describes studies on real catchments i...
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....
Simulation of Water Resources Development Projects in the Nam Kam Basin,Thailand
Water Resources Development Projects Nam Kam Basin
2009/10/28
The Nam Kam basin is located in north east Thailand, discharging into the
Mekong river. At present, a hydropower project has been constructed in the
basin, and Nong Han, a natural lake, is regulated...
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...
Digital Simulation Model for Brine Coning in Unconfined Anisotropic Aquifers
Digital Simulation Model Unconfined Anisotropic Aquifers
2009/10/27
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...
Simulation of Soil Frost Depth and Effect on Runoff
Simulation Soil Frost Depth Effect on Runoff
2009/10/27
A physically based soil frost depth model usable with air temperature data and
precipitation data, is presented. Snow depth is calculated from precipitation
data using a physical snow cover model. T...
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...
Simulation of Runoff and Nitrate Transport from Mixed Basins in Sweden
Simulation of Runoff Nitrate Transport Basins in Sweden
2009/10/27
A conceptual model for simultaneous computation of runoff and inorganic
nitrogen leaching is described. The model is semi-empirical with coefficients
that are calibrated against observed data. It ha...
Estimating the Variance of Airborne Snow Water Equivalent Estimates Using Computer Simulation Techniques
Airborne Snow Water Equivalent Estimates Simulation Techniques
2009/10/27
Estimates of snow water equivalent derived from measurements of the attenuation
of terrestrial gamma radiation vary as a function of several known sources
of error. In this study, a computer simulat...
Base Catchment Modeling in Urban Runoff Simulation
Base Catchment Modeling Urban Runoff Simulation
2009/10/26
The selection of numerical model and the transformation of catchment data
into 'input data' are two fundamental problems in urban runoff simulation.
They are discussed from a general point of view. ...
Sensitivity of Streamflow Simulation to Changes in Climatic Inputs
