Construction activities also complicated the identification and interpretation of streamflow responses. Although these data gaps and construction activities did not affect our findings, it was critical to develop a routine protocol for quality control of the instantaneous streamflow data used in this study.

The belt and road initiative, reminiscent of the silk road, is a massive infrastructure project that would stretch from east asia to europe.
To assess the influence of road building and logging on storm flow response, a pair of watersheds were studied at caspar creek near fort bragg in northern california from 1963 to 1975. Selection cutting and tractor yarding of 85-year-old second-growth redwood and douglas-fir forest did not significantly affect large peak streamflows.
Jones and grant (1996) re-analyzed 34 years of streamflow record and found detectable differences in the hydrograph shape associated with clearcutting and road construction. They reported that forest harvesting and associated road construction appeared to increase peak dis-.
Streamflow, precipitation, and water quality monitoring data, along with periodic assessments of geomorphology, will support ncdot construction site inspections by allowing adaptive responses to potential construction impacts and provide the public with readily accessible, objective information regarding conditions in the french broad river.

Building and timber harvest on streamflow, sedimentation, and fish habitat. This paper reports the influence of selection cutting and tractor yarding an 85-year-old second-growth red-wood and douglas-fir forest on storm flow response of cas-par creek in northern california.
Episodic erosion occurs when soils fail in response to storm events or other triggers. These erosion flows during the wet season and less stream flow during the dry season.
Streamflow, or channel runoff, is the flow of water in streams, rivers, and other channels, and is the quickest response times between rainfall and streamflow occur in urbanized areas surface-water withdrawals and transbasin diver.
The streamflow into miyun reservoir, the only surface drinking water source for beijing city, has declined dramatically over the past five decades.
The quickest response times between rainfall and streamflow occur in urbanized areas where yard drains, street gutters, and storm sewers collect overland flow and route it to streams straightaway. Runoff velocities in storm sewer piper can reach 10 to 15 feet per second.
We are pleased to submit our responses to the sierra club kaua’i group’s comments on the 2nd deis for hokua place. The responses to your comments are numbered in concert to your numbered comments. Our responses are as follows: page 1, item 1: the zoning designation has been corrected in the feis.
Timber harvest effects on streamflow were greater for clearcut than for partial-cut areas. After road building occurred in 1997 and timber harvest occurred in 2001, the absolute difference of annual water yield in sw1 and sw2 over the control watershed (sw3) immediately increased about 295 mm and 125 mm in wy 2002, respectively.
Based on monthly streamflow and precipitation data from 1960 to 2010 in the jinjiang river basin of china, standardized precipitation index (spi) and standardized streamflow index (ssi) were used to represent meteorological and hydrological drought, respectively. The response of hydrological drought to meteorological drought under the influence of shanmei reservoir was investigated.
The most studied effect of road building is hydrogeologic degradation, in the form of soil erosion, mass movement, sedimentation and altered stream flow. Diffused soil erosion is among the most common consequences of road building. Erosion may concern all road elements - bed, banks, batter, fill and drains.
Building codes and plan requirements can be complicated and change periodically. We make sure those who build and develop on county land understand the latest rules. Is it designed right, graded properly, and does the project comply with a myriad of laws?.

Dam capacity is greatest in the plateau (13,105 dams) and lowest in lowlands (2389). The main cause of this difference is the length of the stream network.
Software developed at the institute - sotfware is not maintained or updated streamflow analysis and assessment software (ver. 2) this software was developed at the institute for watershed science, trent university, in partnership with the lands and waters branch and the renewable energy program, ontario ministry of natural resources.

In response to potential flaws in the stationarity assumption, the need for new insight concerning potential future changes in streamflow is quickly becoming acknowledged as a critical area of research in the hydrologic sciences [national research council (nrc) of the national academies, 2011, 2012].
Keywords: slope stability; forest roads; surface hydrologic response; alteration of streamflow characteristics following road construction in north central idaho.
The debate regarding peak flow responses to forest clearcutting and road building in the maritime regions of the pacific northwest has attracted much attention over the past several decades and its outcome is an important scientific and operational concern. Although there appears to be general consensus that small peak discharge events are increased following forest management activities.
Watershed, however, streamflow response to a given rain event largely depends there is some evidence that modern road building practices, such as locating.
Deer creek is 311 hectares and has been historically used to study how road building and extensive forest management affect water global analysis of streamflow response to forest management.
Current data typically are recorded at 15- to 60-minute intervals, stored onsite, and then transmitted to usgs offices every 1 to 4 hours, depending on the data relay technique used.
Mar 17, 2020 summer streamflow in industrial tree plantations harvested on 40- to 50-year to study how road building and extensive forest management affect water quality.
Jan 27, 2016 unfortunately, no streamflow data are available for the study region. This helped isolate potential impacts of road construction on topography.
