​ This model is used in a world studies extended essay research. The research question is: In what ways would the water desalination method used in Singapore benefit   water-stressed and economically less developed countries, using Palestine as a case study.
This model retrieved data on Palestine water resources from Authority, Palestinian Water. "Annual status report on water resources, water supply, and wastewater in the occupied State of Palestine 2011." Palestinian Water Authority, Ramallah 13 (2012) 
Data for Singapore desalination process is taken from PUB, Singapore Water Agency, "Singapore Water Story." PUB, Singapore's National Water Agency. N.p., n.d. Web. 25 Feb. 2017.
Data for Palestine population growth was taken from World Bank. World Bank. "West Bank and Gaza Home." The World Bank. N.p., n.d. Web. 25 Feb. 2017.
This model assumes that Palestine population will grow at 2.92% (World Bank, 2015) and average domestic consumption is 90 litres per capita per day(Palestine Water Authority, 2012). This model does not take into account growing demands for industrial and agricultural sector. It also does not show the impact of climate change on Palestine natural water resources.

This is step 3 in making a climate model based on our insights of how trees actively contribute to the cooling capcacity of the Earth.​

In this step we added the reflection of the Earth by the Albedo effect.


With Our-Green-Spine we have discovered new insights how trees / forest / green structures are part of the managing system of controlling the temperature of our Earth via their cooling capacity by using water and influencing the water cycle. We want to translate our insights in a climate model. People who to join us please send an email to marcel.planb@gmail.com.

Develop a daily time step simulation model that consists of a reservoir with a single inflow and single outflow (release)
Use units of million m3 and include any necessary parameters (e.g., capacity k) as separate adjustable variables
Implement the standard linear operating policy (SLOP). 
Assume the reservoir is 500 mcm (k=500). 
Develop yield-reliability results for a target (T) delivery values of 1, 3, 5, and 7 mcm/day.3 
(The mean inflow for the time series is 34.8 m3/s, or 3.0 million m3/day.)

The standard linear operating policy provides a basic rule for reservoir release.

This is step 4 in making a climate model based on our insights of how trees actively contribute to the cooling capcacity of the Earth.​

In this step we added the absorption of Sun Energy by the atmosphere via water vapor. 50% of this energy is radiated to Earth and 50% back into space.

We have made a stock containing the IR that is going back to Earth.

A 'leaky bucket' soil moisture model, based on Guswa et al. (2002). Rain falls as discrete events. The mean depth and frequency of rainfall events are determined by total monthly rainfall and number of rain days. A portion of the rainfall is intercepted by vegetation and evaporates before reaching the soil. The remaining rainfall (throughflow) either infiltrates the soil or, if the soil has insufficient capacity, runs off immediately. Soil water exceeding the field capacity is lost by sub-surface leakage, at a rate determined by the degree of soil saturation. Degree of soil saturation also limits rates of soil evaporation and vegetation transpiration. The partitioning between evaporation and transpiration is influenced by fractional area covered by vegetation.
