Watershed Modeling Using GIS Technology: A Critical Review
Geographic Information System GIS hydrologic processes modeling watershed sensing
2015/8/14
Understanding and managing water resource problems involves complex processes and interactions within the watershed surface and subsurface. The imposition of total maximum daily load (TMDL) regulation...

Identification,verification and validation of process models in wastewater engineering:a critical review
Identification verification validation process models wastewater engineering
2009/12/4
This article presents a critical review of the existing methodologies for process mathematical modelling in the area of wastewater engineering. It is argued that model identifiability is not a major i...
Evaporation from a Snow Cover Review and Discussion of Measurements
Evaporation Snow Cover Review Discussion of Measurements
2009/10/28
Possible evaporation rates from a snow surface with respect to available energy
and vapour pressure deficit in the air are discussed. In literature reported
measurements and measurements carried out...
The Step-Drawdown Test and Non-Darcian Flow:A Critical Review of Theory,Methods and Practice
Step-Drawdown Test Non-Darcian Flow Critical Review
2009/10/28
Step-drawdown tests are usually carried out with succeeding steps of increased
pumping yield, each step of equal duration of 1 hour. The background for this
procedure 1s reviewed, and it is shown, t...
This paper presents a review of groundwater models capable of simulating solute transport
(i.e. advection-dispersion) and equilibrium chemistry processes.
Introductory, basic model components are di...
Swedish evaporation research has gone through a rapid development, and
there is now a need to overview the results. This review presents the research in
a broad sense. The brilliant research by Wall...

Northern Countries Measurement Computation Ice Conditions
2009/10/26
In Canada, Water Survey of Canada, a division of the Water Resources Branch
of Environment Canada, is responsible for the collection and processing of data
from more than 3,300 active streamflow, wa...

2009/10/12
The surface and subsurface area around wells that is delineated with the sole purpose of protecting water supplies from potential contamination is known as a wellhead protection area (WHPA). Federal r...
Groundwater studies using isotopes and noble gases as a tracer：Review and prospect
environmental tracer stable isotope radioactive isotope noble gas groundwater study
2009/7/14
Environmental tracers become a common tool for the groundwater study and a number of methods have been presented in order to understand groundwater flow processes, water budget, origins, chemical reac...
Literature review of stemflow generation and chemical characteristics in Japanese forests
Stemflow generation Understory tree Chemical characteristics Acidification Forest management
2009/7/14
Stemflow has a significant influence on hydrological and ecological processes within forests. However, research on stemflow is scant as stemflow comprises a very small volume compared to throughfall. ...
The geomorphological unit hydrograph – a critical review
geomorphological unit hydrograph instantaneous unit hydrograph
2009/5/27
The theory of the geomorphological unit hydrograph (GUH) is examined critically and it is shown that the inherent assumption that the operation of the drainage network may be modelled by a correspondi...
The FORGEX method of rainfall growth estimation I：Review of requirement
rainfall growth rainfall depth T-year extreme value
2009/5/26
A growth factor is the ratio of the T-year extreme value to an index extreme value such as the mean of annual maxima. Whereas a record length of ten or more years may suffice to estimate the index va...
