This paper addresses the current imperative to develop and test urban ET algorithms, incorporate these into urban water balance models, and develop these into tools to underpin and guide Water Sensitive Urban Design (WSUD) and integrated urban water management. Two approaches to modelling the urban water balance focusing specifically on urban evapotranspiration are presented: i) SUES (Single-so...

Eine ressourcenschonende Bewässerung von Nutzpflanzen wird durch den Klimawandel in den nächsten Jahren immer größere Bedeutung gewinnen. Eine Möglichkeit, das für Pflanzen zur Verfügung stehende Wasserpotential beurteilen zu können, ist die Nutzung von klimatischen Faktoren und Computermodellen. In diesem Beitrag wird die Entwicklung eines auf dem Forschungsprojekt agriOpenLink basierten Softw...

Evapotranspiration is arguably the least quantified component of hydrologic cycle. We propose two complementary strategies for estimation evapotranspiration rates and root water uptake profiles from soil-moisture sensor-array data. One our implementation ensemble Kalman filter (EnKF); it treats sink term in Richards equation, rather than soil moisture, as observable to update. The other a maxim...

The estimation model was constructed to estimate the evapotranspiration and canopy interception from the forest stand using the parameters showing the forest structure such as stem density, tree height and leaf area index. This model is expected to have the ability to estimate the effect of forest management such as stem thinning and leaf amount control. Comparing the calculated rate by this mo...

This paper presents a method for the estimation of the soil heat flux that was used to determine the evapotranspiration in ecosystems. The great advantage of this approach is that there is the possibility to use this method for both daytime and nighttime as well as that the parameters are adaptively recalculated depending on three soil temperatures. It enables the estimation in situ of the soil...

this study aimed at determining the evapotranspiration and crop coefficient (kc) of sugar beet during the plant growth using drainage lysimeter by using water balance and experimental methods for three years in shahrekord. after sugar beet planting and out of lysimeter, evapotranspiration was measured weekly and monthly by measuring the factors of the water- balance equation. results showed tha...
