Economic ideas and processes are becoming increasingly integrated with more traditional engineering and hydrologic models of water management problems. Combining economic management concepts and performance indicators with an engineering-level of understanding of a hydrologic system can provide results and insights more directly relevant for water management decisions and policies. When such mo...

The 2003 flood of the Muda River reached 1,340 m3 /s at Ladang Victoria and adversely impacted 45,000 people in Malaysia. A flood control remediation plan proposed a levee height based on a 50-year discharge of 1 ,815 m3 /s obtained from hydrologic models. This design discharge falls outside the 95% confidence intervals of the flood frequency analysis based on field measurements. Instream sand ...

Abstract. We revisit three variants of the well-known Stommel diagrams that have been used to summarize knowledge characteristic scales in time and space some important hydrologic phenomena modified these focusing on spatiotemporal scaling analyses underlying processes. In present paper we focus soil formation, vegetation growth, drainage network organization. use existing relationships for gro...

[1] Rising surface air temperatures in response to anthropogenic forcing are intensifying the global hydrologic cycle. Some of the more dramatic signs of climate change are increasing precipitation, evaporation, and freshwater discharge in continental river basins draining to high-latitude oceans. At regional scales, however, an acceleration of the hydrologic cycle is not always detected. In co...

Scientists and engineers understand and communicate hydrologic concepts with the one-word or two-word form of ‘‘groundwater’’ or ‘‘ground water,’’ with care toward consistency in their usage. Both forms certainly mean the same thing. Scientists and engineers also want to improve the public’s scientific understanding of water resources to ensure their future quality and availability. Language pr...

Documenting the recovery of hydrologic functions following perturbations is important to addressing issues associated with land use change and ecosystem restoration. Floodplains on the Santee Experimental Forest were used historically for rice cultivation in the early 1700s; those areas now support bottomland hardwood forests typical of the region. Recently acquired LIDAR data for the Santee Ex...

The purpose of this position paper is to introduce the prototype of a design product knowledge representing system which is theoretically guided by our recent work on extending Function-Behaviour-Structure ontology. The basic constructions and data-storing strategies are presented in the paper along with its major interface, thus to give an outline of the working pattern of this system.
