The Spring Creek Representative and Experimental Watershed Project was initiated in 1965 to understand the effects of land-use conversion from boreal forest to agricultural land on mid-size watersheds typical to northern Alberta. The initial project was deactivated in 1986 and the treatment was never completed. In 1991, Daishowa-Marubeni International Ltd. and the Alberta Department of Environmental Protection restarted the project with new objectives to determine the hydrologic effects of aspen harvesting and the hydrologic recovery of water yield post-harvest. The impacts of basin morphology and forest harvesting on water quality were also investigated. The objectives of this manuscript are to summarize the novel results and data collected for this project.

Effects Of Land Use

An agricultural land with intensive cultivation, large catchments with extended rivers and agricultural population of high-density are the primary reasons for higher pollutant loads in freshwater. However, there are problems in pursuing nutrient losses since several parameters, such as variability in soils and climate are associated with heavy rainfall, especially in tropic regions; plant management, limited resources, and insufficient technical support are not consistent in every crop management. Changes in agricultural practices and unmonitored point sources discharge from watershed, have led to algal bloom in abundance, and thus generated eutrophication at the downstream. The complex watershed processes and forecasting the effects of land use change on water quality can be determined by using tools of watershed models. The Hydrological Simulation Programme-FORTRAN (HSPF) uses lumped parameters, continuous model to predict the long-term evaluation, and deterministic for simulating the water quality and quantity process that occur at the watershed. Pervious land segments (PERLND), impervious land segments (IMPLND), and channel reach (RCHRES) modules were used to determine the general water quality and quantity on Johor watershed. Based on calibration and validation, the HSPF model was capable of simulating different runoff seasons. An increment of 60% in agricultural land had increased the annual mean total phosphorus (TP) load and total nitrogen (TN) load by 3.82% and 5.34%, respectively. A 2-fold increase in agricultural land would result in an approximately 2-fold increase in the quantity of annual TN and TP loads. Between TN and TP loads, TP load has potentially increased more than TN load during the dry, wet, and base-flow years. Upon the long-term of water quality and quantity simulation, this study provides essential knowledge for a method-based runoff and nutrient management plan for the Johor watershed.

Land use conversion in to settlements and agricultural land affect rainwater can not be infiltrate directly in to the soil. Cibiru District has large area with slope so that this region has high risk of erosion. Soil and water conservation activity through tree planting methode  involving comunity services is startegic effort to overcome potential erosion hazzard and increase soil infiltration. The activity of Community services was held from July-August 2018 in Palasari sub-district which has slope 8-15%. This community services methode used in the form of tree planting workshop and supervision during the manintenance periode. This tree planting program was welcomed enthusiastically by the community. The comunity in Cibiru District is pro active in preservation trees, especially during the dry season.

Spatial Plan

Intensive agriculture causes nutrient leaching and accelerates erosion processes, which threatens the good quality status of surface waters, as proposed by the European Union (EU) Water Framework Directive. The purpose of this study was to define the impact of two alternative agricultural land-use change scenarios defined in a Municipal Spatial Plan on surface water quality by using the Agricultural Policy/Environmental eXtender (APEX) model. As experimental area, we chose a small Kožbanjšček stream catchment (1464 ha) situated in the Goriška Brda region in Slovenia. The area, due to favorable conditions for vineyards, is facing increasing deforestation. The change of 66.3 ha of forests to vineyards would increase the sediment, nitrate, and phosphorus loads in the stream by 24.8%, 17.1%, and 10.7%, respectively. With the implementation of vegetative buffer strips as a mitigation measure of the current situation, we could reduce the sediment, nitrate, and phosphorus loads by 17.9%, 11.1%, and 3.1%, respectively, while a combination of the two land-use change scenarios would result in a slight increase of the above-mentioned loads, corresponding to 0.61%, 2.1%, and 6.6%, respectively, compared to the baseline situation. The results confirm that, as we can increase pollution levels with deforestation, we can also reduce water pollution by choosing proper types of land management measures.
