The environmental isotope oxygen-18 was used as a tracer to separate stream
discharge into flows originating from groundwater and fresh meltwater. Two,
mainly forested, watersheds (areas 6.6 and 4.0...
The frequency analysis of flood flows recommended in textbooks yields
different results by the graphical method of plotting on probability paper
using e.g. the Weibull plotting position formula and ...
Time Lag Solution of the Muskingum Flood Routing Equation
Time Lag Solution Muskingum Flood Routing Equation
2009/10/28
Use of time lag in the Muskingum method of flood routing is explained by
considering some specific examples. Time lag method removes undesirable
predicted results which are obtained by the conventio...
A Mathematical Modelling System for Flood Forecasting
Mathematical Modelling System Flood Forecasting
2009/10/28
In this paper comprehensive simulation models are presented which can forecast
the streamflow in real time at various points in river systems and provide a
tool for identifying improvements of the r...
The paper describes the development of new procedures for flood estimation
for dam design in Norway. It summarizes the regulations and recommendations
for flood calculations set forth by "The Norweg...
An Indirect Method for Determination of the Parameters of Flood Plain Aquifers
Indirect Method Determination Flood Plain Aquifers
2009/10/27
An indirect method of determining flood plain aquifer parameters from estimated
autocorrelation of groundwater table data is presented. For this purpose
a stream-aquifer system is approximated by a ...
Proposed Swedish Spillway Design Guidelines Compared with Historical Flood Marks at Lake Siljan
Swedish Spillway Design Guidelines Historical Flood Marks Lake Siljan
2009/10/27
A comparison between the proposed Swedish spillway design floods and historic
flood marks made at lake Siljan in central Sweden, is shown. Frequency
analysis is performed incorporating pregauge info...
Conceptual Modelling of Water Loss on Flood Plains and its Application to River Yamuna Upstream of Delhi
Conceptual Modelling Water Loss
2009/10/26
A water loss module for the river modelling system MIKE 11 has been developed
to account for water losses due to retention and infiltration on flood
plains. MIKE 11 including the water loss module h...
Regional Flood Relationships by Nonparametric Regression
Regional Flood Relationships Nonparametric Regression
2009/10/26
Since some theoretical assumptions needed in linear regression are not always
fulfilled in practical applications, nonparametric regression was investigated as
an alternative method in regional floo...
Characterization of Flood Waves by Rating Curves
Characterization Flood Waves Rating Curves
2009/10/23
The flood waves are characterized within the frame-work of loop (or hysteresis)
of rating curves. The National Weather Service's Dam Break Flood Forecasting
Model is used to generate the flood waves...

2009/10/23
This paper investigates the adaptive use of a simple conceptual lumped rainfallrunoff
model based on a Probability Distributed Model complemented with a
Geomorphological Unit Hydrograph. Three diffe...
A Bivariate Extreme Value Distribution Applied to Flood Frequency Analysis
Bivariate Extreme Value Distribution Flood Frequency Analysis
2009/10/23
This article presents a procedure for use of the Gumbel logistic model to represent
the joint distribution of two correlated extreme events. Parameters of the
distribution are estimated using the me...
Fuzzy Clustering Neural Network as Flood Forecasting Model
Fuzzy Clustering Neural Network Flood Forecasting Model
2009/10/22
Flood forecasting is always a challenge in Taiwan, which has a subtropical climate
and high mountains. This paper develops a fuzzy clustering neural network
(FCNN), and implements this novel structu...
