"This book studies the theory, practice and evaluation methods of international development cooperation, aid and assistance management in detail from a global perspective. It attempts to answer the following questions: How effective are the current Western aid methods? How should China optimize...

It is important to determine how well ETo can be estimated from easily observed Epan (free water evaporation measured by a pan) measurements and the other climatic data. Our objectives are to predict annual ETo with Epan data (with a calibrated kp (=ETo/Epan)) and with a 4-variable regression...

A heat-pulse (HP) sensor installed in a double-layered soil with the heating probe positioned at the layer interface violates the underlying assumption of soil homogeneity for the cylindrical perfect conductors (CPC) theory used to interpret the HP data. In this study, laboratory and numerical...

Saturated hydraulic conductivity (Ks) is a critical soil property affecting water flow and solute transport. In the Loess Plateau of China, sloping farmlands have been increasingly replaced by dam farmlands to achieve higher crop yields and more importantly to control soil erosions. It is...

Identifying representative locations that estimate mean soil water content (SWC) for an area of interest is one of the most important applications of the concept of temporal stability but typically requires extensive sampling on multiple occasions. This study aimed to examine the feasibility of...
