Derivation of Instantaneous Unit Hydrograph for a sub-basin using Linear Geomorphological Model and Geographic Information Systems
Geographic Information System GIS Linear Geomorphological Model LGM GIUH
2015/8/14
Rainfall is converted into runoff and reaches the river and it becomes river flow. Geomorphological Instantaneous Unit Hydrograph (GIUH) based approach, which uses the geomorphologic parameters, is us...

An assessment of future extreme precipitation in western Norway using a linear model
extreme precipitation western Norway linear model
2010/12/22
A Linear Model (Smith and Barstad, 2004) was used to dynamically downscale Orographic Precipitation over western Norway from twelve General Circulation Model simulations. The GCM simulations come from...
Linear advection modelling:the issue of divergent flows
Linear advection modelling issue divergent flows
2009/12/7
Schemes for linear advection modelling in multiple dimensions on structured grids use either time-splitting or an unsplit approach for flux computation. In the case of strongly divergent flows, time-s...
Improved non-linear transfer function and neural network methods of flow routing for real-time forecasting
non-linear transfer function neural network methods flow routing real-time forecasting
2009/12/4
Data-based methods of flow forecasting are becoming increasingly popular due to their rapid development times, minimum information requirements, and ease of real-time implementation, with transfer fun...
A multiple linear regression GIS module using spatial variables to model orographic rainfall
multiple linear regression GIS module spatial variables orographic rainfall
2009/12/4
This paper aims to document the development of a new GIS-based spatial interpolation module that adopts a multiple linear regression technique. The functionality of the GIS module is illustrated throu...
Comparison of quadratic and non-linear programming (QP and NLP) optimization models in groundwater management
quadratic and non-linear programming optimization models groundwater management
2009/12/4
This project is concerned with the comparison of two algorithms used in groundwater management models, based on Quadratic Programming (QP) and Non-linear Programming (NLP) models.A quadratic objective...
Runoff Pattern and Peak Flows from Moving Block Rains Based on a Linear Time-Area Curve
Runoff Pattern Peak Flows Moving Block Rains Linear Time-Area Curve
2009/10/28
One of the most outstanding problems within urban drainage is to give a
statistically correct description of the runoff effect from areal and temporal
distributed rain storms. Due to the large numbe...
Analysis of Non-Linear Rainfall-Runoff Process
Analysis Non-Linear Rainfall-Runoff Process
2009/10/27
Rainfall runoff phenomena in small watersheds are favorably modelled using
the kinematic wave approach. The present investigation considers excess rainfall
as time dependent but ignores spatial effe...

Log-linear, exponential and fractional relations for estimating seasonal snowmelt
from early-spring snow accumulation in the Indus and Kabul river basins
in the western Himalayas are developed with ...
Estimation of Aquifer Parameters by Least-Squares Method under Linear Flow Conditions in Fractured Rocks
Aquifer Parameters Least-Squares Method Linear Flow Conditions
2009/10/26
Pumping and recovery test data in phyllite formations were analysed under linear
flow conditions by incorporating modification in the method proposed by Sen
(1986). Although the Sen (1986) method is...
EQUILIBRIA IN SUBSURFACE FLUIDS WITH LINEAR INTERACTION BETWEEN DECAY AND SORPTION
SUBSURFACE FLUIDS LINEAR INTERACTION SORPTION
2009/10/19
There are many situations in groundwater transport where sorption processes act at the same time.
Equilibria of components in a decay chain, which are known for a single phase system, may remain val...
