This study aimed at opening discussions concerning new ideas of suggesting sustainable scenario based on the principle of an integrated spatial development ring between urban-rural areas along and between AL-Abrash and AL- Hseen rivers watershed, as
an application of the bottom-up planning model, seeking to achieve ruralization in parallel with urbanization. This paper adopted data collections and analysis through using a step-by-step approach. Firstly, investigated the land-cover change (LCC) during 30-years. Therefore, using multi-temporal satellite data from different dates for the same study area to create thematic land cover maps which can be used for land cover change detection. Three Landsat satellite images from1987, 2002 and 2017 were classified separately using the supervised classification method in ArcGIS, to provide an economical way to quantify, map and analyse changes over time in land cover. Then, SWOT analysis for the possibilities and determinants within the two-way flow of the current and futuristic economic activity, besides discussion the opportunities of the land-use (LU) taking into account slop map to achieve conservation priority for natural resources. Finally, evaluate results and establishing a sustainable spatial scenario approachable to upgrade into scaling up/out to covering the coastal region watersheds, can support regional planning and decision-making in the future.
The paper discussed the lack of the river
tourism development on the River Alasi banks although it has a lot of opportunities for an
appropriate riverine tourism, in particular of Hama city, where many recreational and
tourism potential are exist.
Thus the research studied the river tourism to the emerged
within international cities, which depends on multiple natural and human factors located on
the banks of the river, where the luxury tourist boats and several types of Sports River had
been increased
The paper aimed to introduce a field inventory of the tourist potential the banks of
the Alasi River through a field survey identifying the possibilities that exist on the banks of
the River Alasi in Hama city that can be used as a key-core to the fluvial tourism.
Comparing potentials and riverine tourism requirements derived from studying worldwide
models with the status of the riverbanks in the area of research.
International river basins are characterized by their wide extent where mapping earth
surface features and drawing contours by topographic team become–somehow- impossible
because the cost and efforts consumed to execute it become very high and may
exceed
reasonable limits. Here it becomes necessary to use digital elevation models (DEM)
inferred by specialized scientific organizations using remote sensing.
There are several DEMs available on the internet and downloadable for free. The
primary factor in defining the models efficiency in building hydrological models not the
least cost but the maximum reliable results and better resolution that adequate to the
capabilities of the PCs.
In this study, three DEMs were used to derive and build hydrological models for the
Euphrates-Tigris basin using Geographic information system techniques. The resulted
boundaries of Euphrates-Tigris basin were compared with three boundaries implemented
by international research organizations (UNEP, ESCWA, and FAO). As a conclusion of
this comparison, the SRTM—3arc DEM was the most efficient model among used models.
In addition, this study indicated the necessity to reevaluate Basin’s boundaries and correct
the spatial distribution of proportion for basin area between the riparian countries.
This study was carried out during the period 2011–2010 for 12 months. 110 species
of phytoplankton in Al-Kabir Al-Shamali River were identified including 4 species of
Euglenophyta, 15 species of Cyanophyta, 49 species of Chrysophyta, 40 species of
Chlorophyta and 2 species of Pyrrophyta.
Some physicochemical parameters of water were determined. Some of them were the
temperature which ranged between 10.8–28°C, the pH 7.76–8.2 and the BOD 1.6–10mg/l,
while the concentrations of NO3
- ranged between 1.10-250 mg/l, nitrate 0.13-0.01mg/l, and
PO4
- ions 0.015–1.05 mg/l. The highest value of ammonium ions was 6.25mg/l and the
lowest was 0.011 mg/l. BOD concentrations ranged between 6.06-12.07mg/l.
