CALIBRATION OF EFFECTIVE SOIL HYDRAULIC PARAMETERS OF HETEROGENEOUS SOIL PROFILES

Jhorar R.K.; Van Dam J.C.; Bastiaanssen W.G.M.; Feddes R.A. (2004)

Distributed hydrological models are useful tools to analyse the performance of irrigation systems at different levels. For the successful application of these models, it is imperative that effective soil hydraulic parameters ...
ESTIMATION OF GROUNDWATER RECHARGE USING WATER BALANCE COUPLED WITH BASE-FLOW-RECORD ESTIMATION AND STABLE-BASE-FLOW ANALYSIS

Lee C.H.; Chen W.P.; Lee R.H. (2006)

In this paper, the long-term mean annual groundwater recharge of Taiwan is estimated with the help of a water-balance approach coupled with the base-flow-record estimation and stable-base-flow analysis. Long-term mean ...
MODELLING GROUNDWATER FLOW OF THE TRIFA AQUIFER, MOROCCO

El Idrysy H.; De Smedt F. (2006)

Trifa is the most productive agricultural plain of north-eastern Morocco. The development of agricultural activities during the last few decades has been mainly based on imported water for irrigation. However, irrigation ...
PLANTS IN WATER-CONTROLLED ECOSYSTEMS: ACTIVE ROLE IN HYDROLOGIC PROCESSES AND RESPONSE TO WATER STRESS - I. SCOPE AND GENERAL OUTLINE

Rodriguez-Iturbe I.; Porporato A.; Laio F.; Ridolfi L. (2001)

This series of four papers studies the complex dynamics of water-controlled ecosystems from the hydro-ecological point of view [e.g., I. Rodriguez-Iturbe, Water Resour. Res. 36 (1) (2000) 3-9]. After this general outline, ...
PLANTS IN WATER-CONTROLLED ECOSYSTEMS: ACTIVE ROLE IN HYDROLOGIC PROCESSES AND RESPONSE TO WATER STRESS - II. PROBABILISTIC SOIL MOISTURE DYNAMICS

Laio F.; Porporato A.; Ridolfi L.; Rodriguez-Iturbe I. (2001)

A stochastic model for soil moisture dynamics at a point is studied in detail. Rainfall is described as a marked Poisson process, producing a state-dependent infiltration into the soil. Losses due to leakage and ...
PLANTS IN WATER-CONTROLLED ECOSYSTEMS: ACTIVE ROLE IN HYDROLOGIC PROCESSES AND RESPONSE TO WATER STRESS - III. VEGETATION WATER STRESS

Porporato A.; Laio F.; Ridolfi L.; Rodriguez-Iturbe I. (2001)

The reduction of soil moisture content during droughts lowers the plant water potential and decreases transpiration; this in turn causes a reduction of cell turgor and relative water content which brings about a sequence ...
SENSITIVITY OF COMPUTED VALUES OF WATER BALANCE AND NITRATE LEACHING TO WITHIN SOIL CLASS VARIABILITY OF TRANSPORT PARAMETERS

Vachaud G.; Chen T. (2002)

Variability with respect to model input data is recognised as a potential source of uncertainty in model predictions. The aim of this study is to estimate the sensitivity of computed values of water balance terms, in ...
SHORT-TERM EVAPORATION AND WATER BUDGET COMPARISONS IN SHALLOW ARCTIC LAKES USING NON-STEADY ISOTOPE MASS BALANCE

Gibson J.J. (2002)

Shallow lakes in a continental, low Arctic setting are found to undergo substantial fluctuations in heavy-isotope content during the annual cycle due to extreme seasonality in water balance processes. Progressive isotope ...
WILL THE RIVER IRTYSH SURVIVE THE YEAR 2030? IMPACT OF LONG-TERM UNSUITABLE LAND USE AND WATER MANAGEMENT OF THE UPPER STRETCH OF THE RIVER CATCHMENT (NORTH KAZAKHSTAN)

Hrkal Z.; Gadalia A.; Rigaudiere P. (2006)

The Irtysh river basin all the way from river spring in China across Kazakhstan as far as the Russian part of Siberia is among the most ecologically endangered and affected regions on our planet. The study provides a summary ...
